Feminism is not encouraging ballbusting as a means of dealing with things, as hot as that would be. In fact they're trying to empower boys as well as everyone else to be able to talk about boundaries and to have their bodily autonomy respected. If there's an increase in images of ballbusting it's more because we exist as an audience who enjoys watching it than because of anything to do with feminism. Some individual feminists are messed up of course but overwhelmingly the larger problem is the agency and boundaries of women being abrogated for the benefit of men. There's backlash against that, and backlash against the backlash, but the way forward is to help women feel listened to and not disrespected, and to support boys to grow up with emotional competence and with a clear understanding of the importance of not imposing oneself on another, but instead establishing mutual respect and reciprocity. There's a long way to go still but many feminist thinkers have contributed to that. Anyway don't blame them because some pervy animator catered to your fetish in a video that's ridiculous.
